NOTE It is important for the alignment procedure, that no significant
atmospheric visibility variations occur during the procedure. For this
reason, it is recommended to do the procedure in weather conditions that
are stable without precipitation and with visibility above 10 km.
To make sure that the transport protection in the transmitter and receiver
measurement unit have been removed, the user has to give a
confirmation. See Figure 129 below and the example below:
HAS THE TRANSPORT PROTECTION IN THE T/R OPTIC UNITS BEEN
REMOVED? (yes/no) :
To confirm, type
yes<CR>.
To abort the action, type
no<CR>
.
As the current position of all axes will be lost, the user has to confirm the
movement to the mid position for all axes. See the example below:
Move Optics To Mid Position. Are You Sure? (yes/no):
To confirm, type
yes<CR>
.
To abort the action, type
no<CR>
.
Now all axes are moved to the mid position, one by one. Indication of the
process is given on the left of the menu.
